摘要
无功对电力系统的经济、安全和可靠运行具有重要的作用,因此必须对无功的成本和价值进行分析,才能科学解决无功定价问题。鉴于有大量的文献对无功生产成本做了分析,该文从系统侧阐述了不同节点发电机发出或吸收的无功对系统电压和网损的影响,从而提出了基于网损灵敏度和无功灵敏度的分析方法,合理地说明了发电机无功对系统价值,并以算例进行说明。
Reactive power is important to the economic,secure and reliable operating of power system. In order to solve the pricing problem of reactive power scientifically, its cost and value should be analyzed. Many papers analyzed the cost of reactive power from production side. This paper expounds the effects of producing or absorbing reactive power in different generator nodes to the voltage and net loss from system side. What＇s more ,it puts forward the method of sensitivity analysis based on net loss and reactive power to illus trate system value of generators reactive power rationally. An exemple is introduced for validating the method.
